First Advance Estimates of National Income, 2020-21
The National Statistical Office , Ministry of Statistics and Programme Implementation has released the First Advance Estimates of National Income at both Constant  and Current Prices, for the financial year 2020-21 along with the corresponding estimates of expenditure components of the Gross Domestic Product .
2. The First Advance Estimates of GDP have been released in accordance with the release calendar of National Accounts. The approach for compiling the Advance Estimates is based on Benchmark-Indicator method. The sector-wise Estimates are obtained by extrapolation of indicators like  Index of Industrial Production  of first 7 months of the financial year,  financial performance of Listed Companies in the Private Corporate sector available upto quarter ending September, 2020  1st Advance Estimates of Crop production,  Accounts of Central & State Governments,  information on indicators like Deposits & Credits, Passenger and Freight earnings of Railways, Passengers and Cargo handled by Civil Aviation, Cargo handled at Major Sea Ports, Sales of Commercial Vehicles, etc., available for first 8 months of the financial year. Projections for 2020-21 for Freight earnings of Railways, Passengers and Cargo handled by Civil Aviation, Cargo handled at major Sea Ports were also made available by the concerned agencies which were made use of in compilation of estimates of respective sectors. With the introduction of Goods and Services Tax  from 1st July 2017 and consequent changes in the tax structure, the total Tax Revenue used for GDP compilation include non-GST revenue and GST revenue. For the year 2020-21, the Budget Estimates of Tax Revenue as available on the website of Controller General of Accounts  and Comptroller and Auditor General of India  have been used for estimating taxes on products at Current Prices. For compiling taxes on products at Constant Prices, volume extrapolation is done using volume growth of taxed goods and services and aggregated to get the total volume of taxes. Information available on Revenue expenditure, Interest payments, Subsidies etc. based on detailed analysis of budget documents of Centre and States for 2020-21 were also put to use. Extrapolation for indicators like IIP were used to be done by dividing the cumulative value for the first 7 months of the current financial year by average of ratio of cumulative value of 7 months to the annual value of past years. In the current pandemic led scenario, where wide fluctuations are noted in the month-wise indices with a significant drop especially in the first quarter, the usual projection techniques won’t hold good. Necessary modifications were accordingly made in extrapolating the indices based on the available information. Percentage change in the main indicators used in the estimation are given in the Annexure.
3. Real GDP or GDP at Constant Prices  in the year 2020-21 is likely to attain a level of ₹134.40 lakh crore, as against the Provisional Estimate of GDP for the year 2019-20 of ₹145.66 lakh crore, released on 31st May 2020. The growth in real GDP during 2020-21 is estimated at -7.7 per cent as compared to the growth rate of 4.2 per cent in 2019-20. Real GVA at Basic Prices is estimated at ₹123.39 lakh crore in 2020-21, as against ₹133.01 lakh crore in 2019-20, showing a contraction of 7.2 percent.
4. Nominal GDP or GDP at Current Prices in the year 2020-21 is likely to attain a level of ₹194.82 lakh crore, as against the Provisional Estimate of GDP for the year 2019-20 of ₹ 203.40 lakh crore, released on 31st May 2020. The growth in nominal GDP during 2020-21 is estimated at -4.2 per cent. Nominal GVA at Basic Prices is estimated at ₹175.77 lakh crore in 2020-21, as against ₹183.43 lakh crore in 2019-20, showing a contraction of 4.2 percent.
5. With a view to contain spread of the Covid-19 pandemic, certain restrictions were imposed from 25 March, 2020. Though the restrictions have been gradually lifted, there has been an impact on the economic activities as well as on the data collection mechanisms. The data challenges in the case of other underlying macro-economic indicators like IIP and CPI, used in the estimation of National Accounts aggregates will also have implications on these estimates. Further, the projected indices may significantly vary from the actual indices which in turn will depend on the pandemic led economic situation prevalent during those months and specific measures, if any, taken by the government.
6. Estimates are therefore likely to undergo sharp revisions for the aforesaid causes in due course, as per the release calendar. Users should take this into consideration when interpreting the figures.
7. Estimates of Gross/Net National Income and Per Capita Income along with GVA at Basic Prices by kind of economic activity and the Expenditures of GDP for the years 2018-19, 2019-20 and 2020-21 at Constant  and Current Prices are given in Statements 1 to 4.
8. The release of Second Advance Estimates of National Income for the year 2020-21 and quarterly GDP estimate for the quarter October-December, 2020  will be on 26.02.2021.
